No sex drive?

Hi ladies. I am chronically ill and since I’ve been in a flare for about a month now - I’ve had no sex drive not before my period, not when I have my period, and not even after when I’m ovulating. I don’t know i am just not appealed to it at all by my boyfriend and I love my boyfriend and wanna love on him but I just don’t have any sex drive at all. I don’t know if it’s because I’m in a flare up (I have Lupus) and I’m in pain all the time and exhausted from Lupus itself or if I should be concerned or not. If anyone has answers please let me know. Thanks.

Yes we use protection - no I am not pregnant.
